Multi-layered support structure

Abstract

A multi-layered support structure provides ergonomic, adaptable seating support. The multi-layered support structure includes multiple cooperative layers to maximize global comfort and support while enhancing adaptation to localized variations in a load, such as in the load applied when a person sits in a chair. The cooperative layers each include elements such as pixels, springs, support rails, and other elements to provide this adaptable comfort and support. The multi-layered support structure also uses aligned material to provide a flexible yet durable support structure. Accordingly, the multi-layered support structure provides maximum comfort for a wide range of body shapes and sizes.

Description

PRIORITY CLAIM[0001]This application claims priority to both of U.S. Provisional Patent Application No. 61 / 135,997, filed Jul. 25, 2008, titled MULTI-LAYERED SUPPORT STRUCTURE, and U.S. Provisional Patent Application No. 61 / 175,670, filed May 5, 2009, titled MULTI-LAYERED SUPPORT STRUCTURE, which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]The invention relates to load support structures. In particular, the invention relates to multi-layered seating structures.[0004]2. Related Art[0005]Most people spend a significant amount of time sitting each day. Inadequate support can result in reduced productivity, body fatigue, or even adverse health conditions such as chronic back pain. Extensive resources have been devoted to the research and development of chairs, benches, mattresses, sofas, and other load support structures.[0006]In the past, for example, chairs have encompassed designs ranging from cushions to more complex combinations of ...

AI Technical Summary

Benefits of technology

[0011]Accordingly, the multi-layered support structure includes cooperative yet independent layers, with each layer including cooperative yet independent elements, to provide maximized global support and comfort to an applied load while also adapting to and supporting localized load irregularities. Further, the load support independence provided by the multi-layered support structure allows specific regions to adapt to any load irregularity without substantially affecting the load support provided by adjacent regions.

Problems solved by technology

Most people spend a significant amount of time sitting each day.

Inadequate support can result in reduced productivity, body fatigue, or even adverse health conditions such as chronic back pain.

Some discomfort, however, may still arise even from the improved seating structures.

This may result in discomfort as the seating structure presses the wallet or other body shape irregularity up into the seated person's backside.
